The actual vendor and technology specific management is captured in the Technology Management functionality that manages the different technical domains that may exist. This is the implementation of the specific management interfaces that depend on the technology and vendor in question. The functionalities that are part of the Technology management in the Technical domains are to be exposed by APIs that can be consumed by the Resource management and orchestration and/or the Service management and orchestration component depending on the implementation. The exact set of functionalities and APIs exposed by the Technical domains depends on the nature of the technology and its architectural implementation. These functionalities can be consumed by the Resource management and orchestration or E2E Service management and orchestration, depending on the implementation.
The production domain interfaces with the GCS technical domain via the OpenNSA agent and its management console station. This is done via the TMForum Activation and Configuration Open API that can be used to provision new circuits, query or change the status of a provisioned circuit, and terminate a circuit and the results are stored in the service and resource inventory as appropriate.
